ROLLERI-SKATVE. A

SPECIFICATION forming part of Letters Patent No. 648,398, dated May 1, 1900. 7

Application filed January 28, 1899. Serial No. 703,669. (No model.) 7

5 Massachusetts, have invented a new and useful Roller-Skate, of which the following is a specification.

The object of my present invention is to provide a simple, inexpensive, and attractive IO form of roller-skate; and the especial object of my invention is to provide an improved. form of skate-wheel in which the ball-cas'f ings will be supported and locked in place in a rigid and efficient manner and to provide an improved construction for excluding dust from the bearings. To these ends myinvention consists of the skate-wheels, as hereinafter described, and of the combinations of parts, as hereinafter more particularly pointed out in the claim at the end of this specification.

In the accompanying drawings, Figure 1 is a side View of a roller-skate construct-ed ac: cording to my invention, one of the rear dust- Washers being removed. Fig. 2 is an enlarged plan view, partially in section, of a rocker and skatewheels carried thereby; and

Fig. 3 is a perspective view, partially in section, illustrating the pieces employed for sup porting and locking the ball-casings in the skate-wheels.

To journal a skate-wheel or ball-casingsso that the same will always run substantially true, it is essential that the ball-casings should. be locked in the wheel-bodies, so that the same cannot turn therein. Furthermore, where skate-wheels are kept in stock or are taken off from skates it is essential that the ball-casings should be prevented from falling out of place in the skate-bodies. In prior constructions, as shown, forexample, in patent to Daniel, No. 352,739, of November 16, 1886, it has been customary to press or secure the ball-casings in the skate-wheels with a tight driving fit. This practice I have found to be objectionable, as a considerable number of skate-wheels are cracked or weakened in manufacture, and even when'these parts-are put together with a driving fit the ball-cas- 50 ings are apt to work loose on account of the shrinkage of the wheel-body.

In assembling a skate-wheel of my construction I preferably make the bushing an easy fit for the skate-body and fit the ballcasings to the bushing with a tight driving fit, so that when the ball-casings are pressed or driven into place the bushing will be slightly expanded inside of the Wheel-body. The bushings are preferably long enough to extend slightly from the face of the skatewheels, and to exclude dust from the bearings I preferably provide the axles with dishshaped dust-washers, which fit over the ends of the bushings. its ball-casings in the skate-wheel, I prefer ably notchothe ends of the ball-casings and bushing, and riveted on opposite sides of the wheels I employ locking-washers having tongues engaging the notches in the bushings and ball-casings.

Referring to the drawings and in detail, A

designates the foot-plate or body portion of a sockets in the lower end of the rockers. The

rockers D are normally held in alinement by means of rubber cushions or by springs in the ordinary manner. Secured in or carried by the rocker-pieces D are the studs or axles 10, having dust-washers 12 and ball-cones 11 secured thereon. Secured on the outer ends of the axles 10 are adjustable ball-cones 20, which may be locked in place by nuts 21, washers 22, and dust-washer 12.

The skate-wheels which I employ preferably comprise annular wheels or skate-bodies 13, fitting into each of which is a bushing 14. Driven into the bushings 14 and preferably separated from each other by a spacingwasher 16 are ball-casings 15. The bushings 14, as before explained, are first fitted loosely into the skate-wheels, and when the ball-casings are driven therein these bushings are To lock the bushing and slightly'expanded, so as to then fit tightly in place in the skate-wheels. The bushings are preferably long enough to extend a short distance from the face of the skate-wheels, and in order to look a bushing and its ballcasings in position in each skate-wheel the ends of the bushing and its ball-casings are notched transversely, as at 1'7. V

Secured on opposite faces of the skate-wheel and preferably riveted together through the wheel-body are locking-Washers 18, having inwardly-projecting tongues 19 for engaging.

the notches 17. i

The dust-Washers 12, which fit slightly over the ends of the bushings 14, I have found to be an efficient means for excluding dust from the bearings, and by the oonstruction of skatewheel described I have provided a Wheel in which the ba1l casin gs are accu rately centered with respect to the wheel and are rigidly sou p-- ported, so' that the wheels are not liable'to run out of true even when used for a longtime. Furthermore, by this form of skate-wheel I have provided a constructionin whichthe ball-casin gs are locked in position,so that they cannot work loose or be pulled out from the skate-wheels.

I'am aware that changes may be made in .Letters Patent of the United States, is

- As an article of manufacture, a skate-Wheel comprising a wheel-body 13, a bushing 14 fitting therein, a, spacing-washer '16 and ball casings 15 fitting into said bushing, and locking-washers 18 riveted togetherthrough said vskate-Wheel and having inwardly-extending tongues 19 for engaging notches 17 in the bushing and ball-casings, substantially as described.

' In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
